Santa Ysabel (Spanish for "St. Elizabeth"; Kumeyaay: Ellykwanan),[1] is an unincorporated community in the Santa Ysabel Valley of eastern San Diego County, in southern California.


The 1818 Santa Ysabel Asistencia is located here, a Spanish mission asistencia (sub-mission) of Mission San Diego de Alcalá. The town site is within the former Rancho Santa Ysabel, an 1844 Mexican land grant to José Joaquín Ortega and Eduardo Stokes. In 1878, what began as the town of Santa Ysabel began with a store owned by C. R. Wellington, and grew to include a hotel and a blacksmith.[2] By June 26, 1889, it had acquired its own post office.[3]

The ZIP Code is 92070 and the community is inside area codes 442 and 760.
